China's seven-day repurchase rate, a gauge of interbank funding availability in the banking system, surged 139 basis points, to a 10-month high of 5.28% in Shanghai, the biggest since Jan. 20. The reason for the sudden cash crunch, according to Bloomberg, is that subscriptions for the biggest new share sales of the year lock up funds. Twelve initial public offerings from today through Dec. 25 will draw orders of as much as 3 trillion yuan ($483 billion), Shenyin & Wanguo Securities Co. estimated. In other words, the scramble to allocate capital into China's surest way of making money, IPOs, has led to a drying out of general liquidity in the entire market. This in turn forced the PBOC to intervene and inject short-term money loans to commercial lenders in order to prevent the kind of interbank liquidity lock up that emerged in China in June 2013 in the aftermath of the first Taper Tantrum (and which before all is said and done, will likely take place again) and which sent global capital markets around the globe reeling before China resumed its massive liquidity injections which are at the heart of China's debt-fuelled bubble in the first place.
